3828 dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
3829 dnl or adapt to the vendor's definitions to get equivalent functionality,
3830 dnl without losing the common non-POSIX features.
3831 dnl
3832 dnl Parameters:
3833 dnl     $1 is the nominal value for _XOPEN_SOURCE
3834 dnl     $2 is the nominal value for _POSIX_C_SOURCE
